How the ‘why’s drove the ‘what’: Epilogue

“Study hard what interests you the most in the most undisciplined, irreverent and original manner possible” – Richard Feynman As a deeply confused and somewhat optimistic sophomore, I was in a habit of taking witty quotes more seriously than most. The one above, for example, has guided how I have went about studying Machine Learning and related topics for the last two years or so. Then again, as a chemical engineering major in an Indian college with a tragically rigid curriculum, I didn’t have much of a choice. Fast forward a couple of years and after a few online courses, … Continue reading How the ‘why’s drove the ‘what’: Epilogue

Analyze pull requests and Travis builds using Rperform

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. – Martin Golding In previous posts, I had discussed how Rperform can be used to obtain and visualize package performance data. However, real-world software development is a collaborative process. Thus, automating performance testing for your package is not only a good idea, it’s a critical one; testing projects locally might not be good enough. This post will cover usage of Rperform with Travis CI for automated performance testing. More importantly, we will be able to assess performance impact … Continue reading Analyze pull requests and Travis builds using Rperform

Data Science Competitions 101: Anatomy and Approach

I recently participated in a weekend-long data science hackathon, titled ‘The Smart Recruits’. Organized by the amazing folks at Analytics Vidhya, it saw some serious competition. Although my performance can be classified as decent at best (47 out of 379 participants), it was among the more satisfying ones I have participated in on both AV (profile) and Kaggle (profile) over the last few months. Thus, I decided it might be worthwhile to try and share some insights as a data science autodidact. The problem The competition required us to use historical data to create a model to help an organization … Continue reading Data Science Competitions 101: Anatomy and Approach

Obtaining package performance data using Rperform

“In God we trust. All others must bring data.” – W. Edwards Deming In a previous post, I had discussed how Rperform uses the grammar of graphics approach to visualize an R package’s performance in terms of runtime and memory usage. The visualizations contribute significantly towards Rperform’s mission to allow package developers to quantify, analyze and visualize performance. However, at times you, the developer, might want to play with the data instead to perform analysis of your own. After going through this post, that is exactly what you would be able to do. Background If you are new to Rperform, consider … Continue reading Obtaining package performance data using Rperform
